VARNISE BOQTH.

Specification of Letters Patent.

Patented Feb. 21, 1922.

Application filed March 11, 1921. Serial No. 451,604.

To all whom it may concern:

Be it known that 1, Bear D. WOLF, a citizen of the United States residing at Minneapolis, in the county of llennepin and State of Minnesota, have invented certain new and useful Improvements in. Varnish Booths, of which the followin is a specification.

My invention re ates to varnish booths, and an object is to provide an apparatus by means of which furniture and other articles may be coated with varnish or other coating material in an expeditious and convenient manner. Another object is to provide an apparatus of this character in which the reater part of the surplus coating material is collected and saved for further use at the same time that the fumes and light particles are carried away. i

The full objects andadvantages of my invention will appear in connection with the detailed description, and the novel features embodied in my inventive idea will be particularly pointed out in the claims.

In the accompanying drawings,--

Fig. 1 is a view substantially in central vertical section of my apparatus. Fig. 2 is a fragmentary view in side elevation; Fig. 3 is a front elevational view. Fig. 4 is a view in vertical section on the line 4-4 of Fig. 1. Fig. 5 is a top plan view; Fig. 6 isa front elevational view of a slight modification, a small. portion belng shown in section. Fig. 7 is a fragmentary view in section, and at right angles to the view as shown in Fig. 6.

As shown in the drawings, I provide a. boxlike structure open at the front and having two side walls 10 and 12 and a top wall 14. At the rear of this boxlike structure is a chamber 16 which has side walls 18 and 20 attached respectively to the side walls 10 and 12,-and converging rearwardly. The top of this chamber is formed by a wall 22 and the bottom is constituted by a wall 24 which starts at a place toward the bottom of the apparatus and curves upwardly in a rearward direction to the top of the chamber. The upper portion of the wall 24 has side portions 26 which incline toward the middle and the lower portion of the wall 24 is shaped to form two troughs 28 and 30 At the lower edge of the wall 24 is anupstanding flange 32 which is provided with gaps 34 and 36 at the lower point of the troughs. Through the top wall 22 of the chamber 16 at the rear thereof extends a vertical stack 38 and the forward portion of this top wall is provided W1th an upstanding extension 40 from which a flue 42 extends rearwardly and passes into the stack 38 being curved upwardlyat its rear end within the stack as shown n Fig. 1'. In the front end of the flue 42 is mounted a fan 44 which is driven from a suitable motor 46 mounted on the top Wall 14. The shaft connecting the motor of the fan is protected by a casing 45. As shown in Fig. 2, the stack 38 is provided w th a door 48 and the flue 42 is provided with a. door 50 by means of. which access to these parts respectively may be had. The rear portion of the casing which encloses the chamber 16 is supported in suitable manner as by one or more legs 52. The modified construction shown in Figs. 6 and 7 is for the most part the same as that already described, and so far as applicable, the same reference numerals are used. The form shown in Figs. 1 to 5 has the front portion designed to receive articles such as furni ture which is to be covered with varnish, while the form shown in Fig. 6 and 7 is extended on both sides so as to receive articles of considerable length such as sign boards. For this punpose instead of the side walls 10 and 12, I provide side walls 54 and 56 which are considerably farther from the middle of the apparatus, and these side walls 54 and 56 are joined by a top wall 58 of considerable greater length than the top wall 14. In place of the upstanding extension 40 there is an upstanding extension 60 which is located farther toward the front of the apparatus. Flues 62 and 64 lead out of the top wall 58 near the respective ends thereof and discharge into the extension 60 which is connected to the stack by a flue 42 in the manner previously described.

The operation and advantages of my invention will be readily understood from the foregoing description. The articles t be coated with varnish or other coating maber 16 by the suction produced by the current of air passing up the stack, and these particles are for the most part deposited upon the surface 24 and flow down the gutters 28 and 30 and through the gaps 34 and 36 into any convenient receptacle placed underneath so as to be collected for further use, A receptacle 70 of this character is indicated in Fig. 1.

I claim: I

10 A varnish booth comprising a boxiike structure for receiving articles to be tarnished or coated, a chamber connected with said boxiike structure and having a rearwardly and upwardly extending troughlike bottom wall, a stack extending upwardly from the rear of said chamber a flue extending from the :iront of the booth into said stack, and means for inducing a current of air through said flue discharging into said In testimony whereof i hereunto afiix my signature.
